“…Первые сведения о синтезе и свойствах тетразолсодержащих полимеров появились около 50 лет назад [1], и с тех пор эти полимеры привлекают внимание исследователей-химиков как перспектив ные многоцелевые материалы [2][3][4][5]. Интерес к ним обусловлен наличием комплекса специфических свойств, в частности высокой энергетикой в сочетании с достаточной термостабильностью, значитель ным содержанием азота и совместимостью с широким кругом химических соединений различной при роды.…”

Optimization of the method for the synthesis of methylated poly-5-vinyltetrazole was carried out and it was shown that the process of its preparation, both with the homopolymer acrylonitrile and the commercially available copolymer with methyl acrylate and 2-acrylamido-2-methylpropane sulfonic acid, as starting materials, can be carried out in a single-step apparatus without intermediate release of poly-5-vinyltetrazole. At the same time, the resulting product is identical in composition, structure, and properties to that obtained using a two-stage process. Ability to refuse intermediate release of poly-5-vinyltetrazole allows to reduce the amount of dimethylformamide required for the preparation of methylated poly-5-vinyltetrazole twice, exclude the use of HCl solution from the process, and significantly reduce the time and energy costs of the process.
